Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Can someone suggest me what to do?
I have already changed The ic on the board

By "ic", I assume you mean the ATmega328P. Did you buy an ATmega328P that was advertised as being pre-loaded with a bootloader? If not, you must connect an ISP programmer to your Uno and do a Tools > Burn Bootloader before you will be able to do normal uploads via USB to your Uno.

If you don't own a dedicated ISP programmer, you can use a spare Arduino board as an "Arduino as ISP":
